I know P(c1|x) = p(x|c1).p(c1)
I don't know how to calculate p(x|c1)
I am given 2 vectors in the form (x,y)
and a covariance matrix (2x2)
How do i calculate p(x|c1) from this?
By any chance is this a bivariate normal density?
If so, see Multivariate normal distribution - Wikipedia, the free encyclopedia
